Radium Engineering Injector Seats Top Feed Fuel Rails 25mm Nissan Silvia S15 6cy 99-02

Description

These are the same billet injector seats used in Radium fuel rail kits. They are required when converting an OEM side feed fuel rail to top feed. They simply “pop” into the intake manifold (1 required per injector). They seal to the machined injector counterbore using the included Viton O-ring. The 2 sizes are based on the intake manifold’s inside diameter of each injector counterbore. Below are just a few examples of some popular Nissan engines.
All 30mm injector seats are bright-dipped black anodized. All 25mm injector seats are bright-dipped green anodized. The injector seats are CNC machined with a common 14mm bore for the lower injector O-ring.
